THE 14 CFR PART 91 FLIGHT HAD DEPARTED THE PORTLAND INTERNATIONAL AIRPORT, PORTLAND, OREGON, AT 1200 EDT EN ROUTE TO THE KENT COUNTY INTERNATIONAL AIRPORT, GRAND RAPIDS, MICHIGAN. THE CAPTAIN REPORTED THAT AT APPROXIMATELY 11,400 FEET MSL, IT APPEARED THAT THE AIRPLANE WAS GOING TO DESCEND BELOW THE ASSIGNED LEVEL OFF ALTITUDE OF 11,000 FEET MSL. THE FIRST OFFICER, WHO WAS THE FLYING PILOT IN THE LEFT SEAT, PULLED BACK ON THE AIRPLANE'S YOKE TO INITIATE THE LEVEL OFF WITHOUT DISENGAGING THE AUTOPILOT. THE FIRST OFFICER REPORTED THAT WHEN HE RELAXED THE BACK STICK PRESSURE ON THE YOKE, THE AIRPLANE PITCHED NOSE DOWN APPROXIMATELY 20 DEGREES. A SERIES OF THREE TO FOUR PITCH OSCILLATIONS OCCURRED BEFORE THE AIRPLANE WAS BROUGHT INTO CONTROL. THE CAPTAIN AND FIRST OFFICER AND THE TWO PASSENGERS HAD THEIR SEAT BELTS ON AND WERE NOT INJURED. THE FLIGHT ATTENDANT WHO WAS IN THE AIRPLANE'S GAL LEY RECEIVED SERIOUS INJURIES. THE FLIGHT CONTINUED ON TO GRAND RAPIDS, MICHIGAN, WHICH WAS ABOUT 32 NAUTICAL MILES AWAY, AND AN UNEVENTFUL LANDING WAS MADE. VISUAL METEOROLOGICAL CONDITIONS PREVAILED AND AN IFR FLIGHT PLAN HAD BEEN FILED. THE COCKPIT VOICE RECORDER AND THE FLIGHT DATA RECORDER WERE SENT TO THE NATIONAL TRANSPORTATION SAFETY BOARD FOR EXAMINATION. THE AIRPLANE'S TWO FLIGHT GUIDANCE COMPUTERS (FGC'S) WERE SENT TO HONEYWELL INC. IN PHOENIX, ARIZONA, TO OBTAIN A READOUT OF THE DATA RECORDED WITHIN THE MEMORY OF THE COMPONENTS.

N523AC GULSTM GVSPG550 During INSP/MAINT - WHILE TROUBLESHOOTING AN INTERMITTENT READY LIGHT FOR THE APU INLET DOOR, IT WAS OBSERVED THAT WHEN THE DOOR ACTUATOR RETRACTED, THE SURROUNDING STRUCTURE FLEXED. AFTER ACTUATOR REPLACEMENT, THE REMOVED ONE WAS FOUND TO BE 3/16" TOO SHORT PER THE MAINTENANCE MANUAL SPECS, WHICH WAS LOADING UP THE STRUCTURE. THIS WAS THE ORIGINAL INSTALLED PART FROM THE FACTORY. A SUBSEQUENT CHECK OF ANOTHER G550 FOUND THE SAME CONDITION. MANUFACTURER WAS NOTIFIED. APU HOURS: 625 HRS. VISUAL INSPECTION OF THE SURROUNDING STRUCTURE FOUND NO ANOMALIES. 2017-01-04
N523AC GULSTM GVSPG550 During CLIMB - DURING GEAR RETRACTION, CREW RECEIVED A CAS INDICATION FOR LT MAIN GEAR NOT UP MESSAGE. GEAR CYCLED WITH NO CHANGE INUP INDICATION. RETURNED TO AIRPORT. INVESTIGATION REVEALED THE LEFT STRUT TIE DOWN RING HAD A BENT SPRING WHICH CAUSEDTHE SPRING TO DISENGAGE. THIS DID NOT HOLD THE RING TIGHT TO THE STRUT. WHEN THE GEAR WAS RETRACTED IN THE HORIZONTAL POSITION, THE TIE DOWN RING HUNG VERTICALLY AND PREVENTED THE MAIN DOOR TO CLOSE.

Aviation Datasets Explained


Aircraft Lookup allows anyone to quickly search public datasets published by various aviation administrative services as well as marketplaces and other private aviation data providers in the United States. These datasets provide valuable insight into the history and maintenance record of any aircraft registered in the US. When you provide an N-Number above, we cross reference historical SDR, FAA, and NTSB datasets to identify any relevant records related to that N-Number.

As you may be aware, N-Numbers are not connected to an aircraft for the life of that aircraft - N-Numbers may be deregistered, and re-registered to completely different aircraft. For that reason, please confirm that the details of any search result correspond to the make and model you intended to pull records for.

SDR, FAA, and NTSB databases are provided as follows:

The Service Difficulty Reports (SDR) dataset is defined as "[t]he reports submitted by certificate holders and certificated repair stations, known as service difficulty reports (SDR's), provide the FAA with airworthiness statistical data necessary for planning, directing, controlling, and evaluating certain assigned safety-related programs." This data is, in its raw form, a tab-delimited file with encoded field headers.

The FAA Registration dataset is fairly straightforward - it is a listing of current registrations (along with addresses, aircraft serial number, and other basic metadata) at any point in time. The registration data is a comma delimited file that has named fields at the top of each file. The FAA provides historical data on their site for the previous few years.

The FAA Accident/Incident dataset covers a range of accidents and incidents that may or may not overlap with NTSB data. Typically, more significant crashes are covered by NTSB data while less significant crashes are more comprehensively covered by the FAA Accident/Incident data, which will frequently include minor events like gear-up landings and so forth. The data provided by the FAA is in a tab-delimited file with encoded field headers.

The NTSB investigation dataset is distinct from the FAA dataset. While the number of accidents or incidents they cover are less numerous, the depth at which they are covered is significantly deeper when reported by the NTSB. While each record from the NTSB contains incredible amounts of metadata related to people responsible for the flight, prevailing meteorological conditions at the time of flight, and passengers aboard, this aircraft lookup tool only provides basic summary data. The full dataset is provided as a series of Microsoft access file databases on the NTSB site.
